这项工作的目的是证明使用诊断超声系统（Siemens AnglomerTM和CH6 - 2曲线阵列）的可行性：1）使用自定义M模式序列消融离体肝脏; 2）使用2-D声辐射力脉冲（ARFI）成像监测所产生的组织硬化。在消融前后以及消融序列期间以5 s间隔拍摄图像，以便在时间上监测消融损伤形成。在距离肝脏表面1.5 cm的深度处产生消融损伤，在B模式下不可见。ARFI图像显示肝脏变硬并发热，与大体病理学中变色区域相对应。正如预期的那样，观察到ARFI图像中消融病变的对比度随着消融病变尺寸的增加而增加。本研究证明了使用自定义射束序列的诊断系统定位消融部位、将该部位加热至不可逆损伤点并通过ARFI成像监测消融损伤形成的能力。
The goal of this work is to demonstrate the feasibility of using a diagnostic ultrasound system (Siemens Antares™ and CH6-2 curvilinear array) 1) to ablate ex vivo liver with a custom M-mode sequence and 2) to monitor the resulting tissue stiffening with 2-D Acoustic Radiation Force Impulse (ARFI) imaging. Images were taken before and after ablation, as well as in 5 s intervals during the ablation sequence in order to monitor the ablation lesion formation temporally. Ablation lesions were generated at depths up to 1.5 cm from the surface of the liver and were not visible in B-mode. ARFI images showed liver stiffening with heating that corresponded to discolored regions in gross pathology. As expected, the contrast of ablation lesions in ARFI images is observed to increase with ablation lesion size. This study demonstrated the ability of a diagnostic system using custom beam sequences to localize an ablation site, heat the site to the point of irreversible damage, and monitor the formation of the ablation lesion with ARFI imaging.
